If you are a registered patient and an officer finds your medicine during a traffic stop, the stop usually turns on three things: the packaging, the card, and whether anyone was using it in the car. I’m Rocky Brancato, founder of The Brancato Law Firm, P.A., a Tampa criminal defense firm, and a former Chief Operations Officer of the Hillsborough County Public Defender’s Office, where I oversaw a staff of over 100 attorneys. Our attorneys defend patients, caregivers, and drivers charged with marijuana and paraphernalia offenses in Hillsborough, Pinellas, and Pasco Counties, and we file motions to suppress when a search was based on the smell of cannabis.

What Are the Rules for Carrying Medical Marijuana in a Car in Florida?

The rules come from the patient-protection section of Florida’s medical marijuana law. Under section 381.986(14)(a), Florida Statutes, a qualified patient or caregiver may buy marijuana and a delivery device from a medical marijuana treatment center (MMTC) and may possess up to a 70-day supply, or the greater of 4 ounces of marijuana in a form for smoking or the amount the Department of Health approves, and “all marijuana purchased must remain in its original packaging.” The statute has no separate transport permit; these possession rules travel with the patient.

The statute does not require a locked container or the trunk. Keeping the sealed package out of reach and out of sight is a practical choice, not a legal requirement, and it helps show the marijuana was being carried rather than used.

What Happens If Medical Marijuana Is Not in Its Original Packaging?

Marijuana outside its original packaging falls outside the protection in section 381.986(14)(a), which is the provision that exempts patients from Florida’s drug laws. That can leave a patient exposed to a possession charge under section 893.13, Florida Statutes, even with a valid card. A loose bud in a cup holder, a pre-roll in a cigarette pack, or a vape cartridge in an unmarked case are the situations we see most.

In those cases our attorneys pull the patient’s registry record, the dispensary purchase history, and the product label to show the marijuana was lawfully bought by a registered patient. Prosecutors often decline or reduce a possession charge when the records line up. Our Tampa drug crimes attorney page explains how we defend possession cases, and our guide to how much weed is a felony in Florida covers the possession thresholds.

Can a Medical Marijuana Patient Have a Pipe or Bong in the Car?

Yes. Under section 381.986(14)(b), a qualified patient or caregiver “may purchase and possess a marijuana delivery device intended for the medical use of marijuana by smoking from a vendor other than a medical marijuana treatment center.” Other delivery devices, such as vaporizers sold with cartridges, are covered when bought from an MMTC under section 381.986(14)(a).

For someone without a registry card, the same pipe can be charged under section 893.147(1), Florida Statutes, which makes using or possessing drug paraphernalia with intent to use it a first-degree misdemeanor, punishable by up to 1 year in jail and a $1,000 fine. Residue in a pipe can also support a possession charge, so the patient’s registry status is usually the first fact we confirm.

How Many People in Florida Carry Medical Marijuana?

Close to a million. According to the Florida Department of Health’s Office of Medical Marijuana Use weekly update for July 24, 2026, 938,435 qualified patients held active registry ID cards, and MMTCs operated 771 dispensing locations statewide.

With that many patients, Tampa Bay officers see dispensary bags in cars every day. That is one reason Florida courts have reconsidered whether the smell of cannabis, by itself, still tells an officer that a crime is happening.

Can Police Search Your Car Because They Smell Marijuana in Tampa?

Not on smell alone, under current law in the Second District. In Williams v. State, 421 So. 3d 809 (Fla. 2d DCA 2025), the full Second District Court of Appeal reviewed a Hillsborough County traffic stop where officers ordered a passenger out and searched the car based only on the odor of cannabis. The court held that “the plain smell doctrine can no longer establish probable cause based solely on the odor of cannabis,” because Florida now allows legal forms of cannabis that cannot be told apart by smell. The odor remains “a valid factor to be considered along with all others under the totality of the circumstances.”

Two limits matter. The court still affirmed Mr. Williams’s probation revocation under the good-faith exception, because the old rule was binding when the officers searched. And the court certified the question to the Florida Supreme Court, so the rule could change. The Second District covers Hillsborough, Pinellas, and Pasco Counties, so Williams binds trial courts here unless the Florida Supreme Court rules otherwise. Our post on the Second District plain smell decision goes deeper.

Science points the same way. Researchers at Iowa State University, in Characterizing the Smell of Marijuana by Odor Impact of Volatile Compounds (PLoS ONE, 2015), found that the compounds with the strongest odor impact, such as nonanal, decanol, o-cymene, and benzaldehyde, are often present in low concentrations. A smell tells an officer about plant chemistry; it does not tell the officer whether the product came from a licensed dispensary.

Can You Get a DUI for Medical Marijuana in Florida?

Yes. A registry card is not a defense to driving under the influence if marijuana impaired the driver’s normal faculties. Using marijuana in a vehicle is a separate first-degree misdemeanor under section 381.986(12)(c), even when the driver is not impaired. Our guide to marijuana DUI charges in Florida explains how the State tries to prove impairment, and our Tampa DUI lawyer page covers our DUI defense.

How Do Our Attorneys Defend Medical Marijuana Patients?

1. Confirm the registry record. We document the patient’s or caregiver’s card status on the date of the stop. A valid card produced in court defeats the failure-to-present charge.
2. Trace the product. Dispensary receipts, labels, and the registry’s purchase history show the marijuana was lawfully bought.
3. Challenge the search. If the officer relied on odor, we move to suppress under Williams and test what else the officer claims to have seen.
4. Separate carrying from using. A sealed package is not use in a vehicle. We look at where the product was, whether it was opened, and what the video shows.
5. Address impairment separately. In a DUI case, the card does not decide the case; field sobriety videos, drug recognition evaluations, and blood results do.

A person arrested in Hillsborough County sees a judge at first appearance within 24 hours, usually at the Orient Road Jail, and the case is prosecuted by the State Attorney’s Office for the 13th Judicial Circuit. See our Hillsborough County criminal defense attorney page, or our pages for Pinellas County and Pasco County cases.

Frequently Asked Questions About Medical Marijuana Transportation in Florida

Do you have to keep medical marijuana in the trunk in Florida?

No. Florida law does not require the trunk or a locked box; it requires the original packaging, a legal amount, and no use in the vehicle. The Brancato Law Firm still recommends keeping the sealed package out of reach, because it helps show the product was not being used.

What if I forgot my medical marijuana card during a traffic stop?

Failing to show the card is a second-degree misdemeanor, but you cannot be convicted if you produce a card that was valid at the time of arrest in court by your court date. Our attorneys at The Brancato Law Firm handle that filing; our drug crimes defense page has more.

Can a caregiver drive with a patient’s medical marijuana?

Yes, a registered caregiver may possess and carry the patient’s marijuana under the same packaging and amount rules. The Brancato Law Firm confirms the caregiver’s own registry card status, because the caregiver needs a current card too.

Can I drive to another state with my Florida medical marijuana?

Florida’s protection ends at the state line, and federal law still treats marijuana as a controlled substance. The Brancato Law Firm advises patients not to carry marijuana outside Florida or onto federal property.

Is it legal to smoke medical marijuana in a parked car in Florida?

No. Section 381.986(12)(c) makes using marijuana other than low-THC cannabis “in a school bus, a vehicle, an aircraft, or a boat” a first-degree misdemeanor, parked or not. The Brancato Law Firm defends these charges, often alongside a marijuana DUI charge.

Can medical marijuana charges be dropped in Florida?

Yes, when the registry record, purchase history, and packaging show lawful possession, or when the search was based only on odor. The Brancato Law Firm presents those records to the prosecutor early and files a motion to suppress when the search was unlawful.

If officers found marijuana in your car, your bag, or your apartment, the charge on your paperwork turns on details most people never think about: the weight, whether it was flower or concentrate, and whether a lab ever proved it was marijuana and not hemp. I’m Rocky Brancato, founder of The Brancato Law Firm, P.A., a Tampa criminal defense firm, and a former Chief Operations Officer of the Hillsborough County Public Defender’s Office, where I oversaw a staff of over 100 attorneys. Our attorneys defend marijuana and THC cases across Hillsborough, Pinellas, and Pasco Counties, and in many of them the most useful work happens before the State Attorney’s Office decides what to file.

How Much Weed Is a Felony in Florida?

More than 20 grams of cannabis flower is a felony. Under section 893.13(6)(b), Florida Statutes, “If the offense is the possession of 20 grams or less of cannabis, as defined in this chapter, the person commits a misdemeanor of the first degree.” Anything above that falls under section 893.13(6)(a), which makes unauthorized possession of a controlled substance a third-degree felony. Twenty grams is about seven-tenths of an ounce, so the exact lab weight matters.

The charge climbs in steps, from a misdemeanor for a small amount of flower to trafficking above 25 pounds.

Maximum terms come from section 775.082 and section 775.083, Florida Statutes. Our Tampa drug crimes attorney team first checks whether the State charged the right step.

Is THC Illegal in Florida?

THC from marijuana is illegal without a medical marijuana card, while THC within the legal hemp limit is not. Cannabis is a Schedule I substance under section 893.03(1)(c), Florida Statutes, which also lists tetrahydrocannabinols separately. Section 893.02(3) defines cannabis to include “the resin extracted from any part of the plant,” but excludes marijuana dispensed in conformance with the medical marijuana law and “hemp as defined in s. 581.217.”

That is why “possession of tetrahydrocannabinols” or “possession of THC” is such a common charge description. It is the charge prosecutors use for vape cartridges, oils, edibles, and concentrates, and it is usually filed as a third-degree felony under section 893.13(6)(a).

Why Is a THC Vape or Concentrate Usually Charged as a Felony?

Because the 20-gram misdemeanor does not cover resin. Section 893.13(6)(b) states that for the misdemeanor, “the term ‘cannabis’ does not include the resin extracted from the plants of the genus Cannabis, or any compound manufacture, salt, derivative, mixture, or preparation of such resin.” Wax, shatter, hash, and resin oils are therefore felonies at any weight.

The State still has to prove where the THC came from. In State v. Stevenson, 307 So. 3d 784 (Fla. 4th DCA 2020), a Broward County man was charged with a felony for three THC vape cartridges with a total gross weight of 14.04 grams. The State’s chemist could not say whether the THC was resin-derived or synthetic. The Fourth District held he “could be charged with a felony only if the State could make a prima facie showing that the source of the THC substance possessed by the defendant was either artificially produced, cannabis resin, or ‘any compound manufacture, salt, derivative, mixture, or preparation of such resin,'” and affirmed dismissal of the felony with leave to refile it as a misdemeanor. Our attorneys at The Brancato Law Firm raise Stevenson in vape and edible cases where the lab report is silent about the source.

Can the State Prove It Was Marijuana and Not Hemp?

Only with chemical testing. Under section 581.217, Florida Statutes, hemp is cannabis with “a total delta-9-tetrahydrocannabinol concentration that does not exceed 0.3 percent on a dry-weight basis,” and hemp-derived cannabinoids “are not controlled substances or adulterants” when they comply with the section.

The Second District applied that rule to a Hillsborough County case in Campbell v. State, 407 So. 3d 558 (Fla. 2d DCA 2025). Detectives at Tampa International Airport seized two duffle bags holding 50 vacuum-sealed bundles, and the FDLE analyst tested one 24.47-gram sample. The court held that “Legal hemp and illegal cannabis are indistinguishable by appearance, texture, and odor, such that chemical testing to determine the THC content is now needed to avoid misidentification.” When the State counts several packages toward a trafficking weight, it “must chemically test each packet.” The court reversed the trafficking conviction and ordered entry of felony possession instead.

An officer’s description of “green leafy material” is not proof of THC concentration. Our attorneys at The Brancato Law Firm demand the lab report and check exactly which items were tested.

Can Police Search Your Car Because They Smell Marijuana?

Not on odor alone in Hillsborough, Pinellas, or Pasco County. In Williams v. State, 421 So. 3d 809 (Fla. 2d DCA 2025) (en banc), a Hillsborough County passenger was searched after officers stopped the car for an obstructed tag and a rolling stop and smelled cannabis. The full Second District held that “the plain smell doctrine can no longer establish probable cause based solely on the odor of cannabis,” though odor remains a factor in the totality of the circumstances. It receded from its own 2021 precedent to the extent that precedent held smell alone was enough.

Williams himself lost on the good-faith exception, because the officers had relied on the earlier precedent, and the court certified this question to the Florida Supreme Court: “DOES THE PLAIN SMELL DOCTRINE CONTINUE TO APPLY TO ESTABLISH PROBABLE CAUSE BASED ONLY ON THE ODOR OF CANNABIS?” The Fifth District reached a similar result first in Baxter v. State, 389 So. 3d 803 (Fla. 5th DCA 2024) (en banc), holding that “Unless and until the State demonstrates that illegal cannabis has an odor that is distinct from legal cannabis,” the justification for an odor-only detention “no longer exists.” The Sixth District, which covers Polk and southwest Florida, noted the debate in 2026 but did not decide it.

The issue comes up twice: in a motion to suppress before trial, and in the Campbell testing question at trial. Our post on the Second DCA limits on the plain smell doctrine covers the search issue in more depth.

Does a Medical Marijuana Card Protect You From a Possession Charge?

Only when you follow the rules. Under section 381.986, Florida Statutes, a qualified patient “may not possess more than a 70-day supply of marijuana, or the greater of 4 ounces of marijuana in a form for smoking” or an amount the department approves, and “all marijuana purchased must remain in its original packaging.”

The protection also ends outside “medical use.” A patient who buys from anyone other than a licensed medical marijuana treatment center “violates s. 893.13” under section 381.986(12)(d), and using marijuana other than low-THC cannabis in a vehicle or in public is a separate offense under section 381.986(12)(c). Carrying dispensary product in the car is allowed; using it there is not.

Our attorneys at The Brancato Law Firm bring the patient’s certification, receipts, and packaging to the prosecutor early. Patients also face a federal firearm question, covered in our post on whether you can own a gun if you use marijuana in Florida, and the card is no defense to impaired driving, as our guide to marijuana DUI in Florida explains.

What If the Marijuana Was Not in Your Pocket?

Then the State has to prove constructive possession. Section 893.13(6)(a) reaches “actual or constructive possession,” which is how passengers, roommates, and drivers of borrowed cars end up charged. Our post on constructive possession in Florida explains how courts decide whether the State has tied the item to you, and our attorneys look closely at who else had access.

When Does Possession Become Intent to Sell or Trafficking?

Intent to sell is a third-degree felony at any weight. Under section 893.13(1)(a), a person “may not sell, manufacture, or deliver, or possess with intent to sell, manufacture, or deliver, a controlled substance,” and cannabis is in the third-degree group. Giving away 20 grams or less with no payment is a first-degree misdemeanor under section 893.13(3).

Trafficking starts above 25 pounds. Under section 893.135(1)(a), Florida Statutes, possession of “in excess of 25 pounds of cannabis, or 300 or more cannabis plants” is a first-degree felony with mandatory minimums.

A plant counts only if it has “some readily observable evidence of root formation, such as root hairs.” After Campbell, the State must also test each package it counts, so our attorneys attack the trafficking weight first.

Did Florida Legalize Recreational Marijuana?

No. Amendment 3, the 2024 adult personal use measure, received 5,950,589 yes votes, or 55.9%, according to the Florida Division of Elections official results. Constitutional amendments in Florida need 60%, so it failed. Hillsborough County voters approved it 382,243 to 277,062, but the statewide total controls.

A follow-up measure will not reach the 2026 ballot. After the Secretary of State directed county election officials to strike about 70,600 petition signatures, the First District upheld that direction and the Florida Supreme Court declined review in March 2026, Insurance Journal reported. Possession without a medical card is still a crime in 2026.

What Changes for Hemp on November 12, 2026?

The federal definition of hemp narrows on November 12, 2026. According to the Congressional Research Service report Change to Federal Definition of Hemp and Implications for Federal Enforcement (December 3, 2025), Public Law 119-37 moves the federal limit to a total THC concentration, excludes final hemp-derived cannabinoid products with “more than 0.4 milligrams of THC per container,” and excludes cannabinoids synthesized or manufactured outside the plant. “The new definition will take effect November 12, 2026.”

Florida’s hemp statute was last amended in 2023 and does not adopt the federal text, so state charges still turn on section 581.217 and its 0.3% delta-9 limit. Our attorneys at The Brancato Law Firm treat a hemp product’s label and certificate of analysis as evidence from the first day.

How Many Drug Arrests Happen in Hillsborough County?

More than ten thousand a year. In 2025, Hillsborough County recorded 10,502 drug arrests, a rate of 666.5 per 100,000 residents, according to FDLE arrest data published by Florida Health CHARTS. That is up from 8,124 in 2024 and 6,914 in 2016, a 52% increase over nine years, while Florida’s statewide total fell from 103,461 in 2016 to 89,562 in 2025.

Pinellas County recorded 5,269 drug arrests and Pasco County 1,817 in 2025. These figures count arrests for all drug categories, since CHARTS does not separate marijuana, and they are arrests, not convictions.

How Do Our Attorneys Fight a Marijuana or THC Charge?

One element at a time:

1. Challenge the search. If the stop or search rested on odor, we file a motion to suppress under Williams and Baxter.
2. Demand lab proof. Under Campbell, the State needs chemical testing of THC content to tell marijuana from hemp, and it must test each package it counts toward a trafficking weight.
3. Test the felony label. For vapes, edibles, and oils, we hold the State to Stevenson’s requirement that it prove a resin or synthetic source.
4. Check the weight. A few grams decide whether the case is a misdemeanor or a felony.
5. Contest possession. In shared cars and homes, we press the State to prove knowledge and control.
6. Show medical compliance. A card, a receipt, and original packaging can end a case.
7. Push for diversion or a no-file decision. Completing a program, or persuading the prosecutor not to file, ends the case without a conviction.

What Diversion Programs Are Available for Marijuana Charges in Hillsborough County?

Several, run through the State Attorney’s Office for the 13th Judicial Circuit, which lists them on its programs page. Its Drug Education and Treatment Reducing Recidivism program (DETRR) “is limited to drug possession cases for low-risk, non-violent offenders,” and a participant who completes the assigned treatment or education and stays arrest-free for six months has the possession charge dismissed.

The office also lists the Adult Pre-Arrest Diversion Program, established in Hillsborough County in July 2017 for people with minimal or no record who commit an eligible misdemeanor, under which no charges are filed if the program is completed; a Misdemeanor Intervention Program for first-time offenders; and Pretrial Intervention for “certain first-time felony offenders.” Our Hillsborough County criminal defense attorney team negotiates entry into these programs, and our representation before charges are filed can put the lab issues and the client’s record in front of the prosecutor before a charging decision.

What Should You Do After a Marijuana Arrest in Tampa?

Act before the first court date. A person arrested in Hillsborough County sees a judge at first appearance within 24 hours and is held at the Orient Road Jail until release, and the State Attorney’s Office then decides what to file. Four steps protect the case:

• Do not explain. Statements about whose bag it was are the State’s best evidence of possession.
• Do not consent to searches. Say so plainly to preserve the suppression issue.
• Keep your records. Save your medical card, receipts, hemp labels, and certificates of analysis.
• Call a lawyer early. Diversion and pre-file options are easiest to reach before the charging decision.

Frequently Asked Questions About Marijuana Possession in Florida

What happens for a first-time marijuana possession offense in Florida?

For 20 grams or less, a first offense is a first-degree misdemeanor punishable by up to a year in jail and a $1,000 fine, and in Hillsborough County many first-time cases qualify for diversion. The Brancato Law Firm checks eligibility for DETRR, pre-arrest diversion, and the Misdemeanor Intervention Program before anything else; see our drug crimes defense page.

Can marijuana possession charges be dropped in Florida?

Yes, through suppression, failed lab proof, or completion of a diversion program such as DETRR. The Brancato Law Firm often contacts the prosecutor before the filing decision through our pre-file advocacy work.

Is a THC vape cartridge a felony in Florida?

It is usually charged as one, because resin-derived THC is excluded from the 20-gram misdemeanor. Under State v. Stevenson, the State must show the THC came from resin or was synthetic, and our attorneys at The Brancato Law Firm hold the lab to that showing in every vape case.

Can police search my car in Florida if they smell weed?

Not on odor alone in Hillsborough, Pinellas, or Pasco County after Williams v. State, though odor can still count with other facts. The Brancato Law Firm reviews the body camera video to see what else the officers claimed, as our plain smell doctrine post explains.

Can I be charged with possession if I have a medical marijuana card?

Yes, if the marijuana did not come from a licensed treatment center, was out of its original packaging, or exceeded the supply limit. Our attorneys at The Brancato Law Firm gather the certification and receipts that show compliance and present them to the prosecutor.

Is hemp flower or delta-8 legal to carry in Florida in 2026?

Under Florida law, hemp within section 581.217’s 0.3% delta-9 THC limit is legal, though the federal definition narrows on November 12, 2026. The Brancato Law Firm treats the product’s label and certificate of analysis as defense evidence, and the Congressional Research Service report explains the federal change.

Serving Hillsborough, Pinellas, and Pasco Counties

The Brancato Law Firm, P.A. is a Tampa-based criminal defense practice. We are not affiliated with any other Brancato-named law firms.

As founder of The Brancato Law Firm, P.A., a Tampa criminal defense firm, and a former police academy instructor, I know how much of a marijuana DUI case rests on one officer’s opinion about a driver’s eyes, speech, and balance. I am a member of the National College for DUI Defense, and I have tried more than 150 jury trials to verdict. Our attorneys defend marijuana and drug DUI cases across Hillsborough, Pinellas, and Pasco Counties by testing that opinion against the video, the lab report, and the science.

Can you be charged with DUI for marijuana in Florida?

Yes. Under section 316.193(1)(a), Florida Statutes, a person commits DUI if the person “is under the influence of alcoholic beverages, any chemical substance set forth in s. 877.111, or any substance controlled under chapter 893, when affected to the extent that the person’s normal faculties are impaired.” Cannabis and THC are controlled under chapter 893, so driving while impaired by marijuana is DUI.

The key words are “normal faculties are impaired.” The State has to prove that marijuana actually impaired your normal faculties while you were driving, which is more than proving you had used it. Our Tampa DUI lawyer team builds the defense around that element, because it is the hardest one for the State to prove in a drug case.

Is there a legal THC limit for driving in Florida?

No. Section 316.193 sets a per se limit only for alcohol, a blood or breath alcohol level of 0.08 or higher. There is no THC number that makes driving a crime by itself, so a marijuana DUI is always an impairment case.

Without a number to point to, prosecutors lean on the officer’s observations and on drug recognition testimony. That is where our attorneys at The Brancato Law Firm focus cross-examination.

Why is THC in your blood not proof of impairment?

Because research shows THC levels do not line up with how impaired a person is. The National Highway Traffic Safety Administration told Congress in Marijuana-Impaired Driving: A Report to Congress (DOT HS 812 440, July 2017) that “the level of THC in the blood and the degree of impairment do not appear to be closely related,” and that “THC level in blood (or oral fluid) does not appear to be an accurate and reliable predictor of impairment from THC.”

A controlled driving study points the same way. In Marcotte and colleagues, Driving Performance and Cannabis Users’ Perception of Safety, published in JAMA Psychiatry in 2022, 191 regular cannabis users were randomly assigned to placebo, 5.9% THC, or 13.4% THC cannabis and then tested in a driving simulator. Driving scores in the THC groups dropped at 30 minutes and 1.5 hours, were borderline at 3.5 hours, and were gone by 4.5 hours. The authors concluded that impairment “cannot be inferred based on … THC blood concentrations.”

The AAA Foundation for Traffic Safety reached a similar conclusion in its 2016 study of DUI arrest data, An Evaluation of Data from Drivers Arrested for Driving Under the Influence in Relation to Per se Limits for Cannabis, finding that “a quantitative threshold for per se laws for THC following cannabis use cannot be scientifically supported.” The foundation reported that 70% of cannabis-positive DUI arrestees in its data had THC levels below 5 ng/mL. Our attorneys at The Brancato Law Firm use these sources with defense toxicologists to show a jury why a positive test is the start of the question.

How do police test for marijuana after a DUI arrest in Florida?

Usually with a urine test, and sometimes with blood. Under section 316.1932, Florida Statutes, a driver lawfully arrested for DUI has consented to a urine test, which “must be incidental to a lawful arrest and administered at a detention facility or any other facility, mobile or otherwise, which is equipped to administer such tests … in a reasonable manner that will ensure the accuracy of the specimen and maintain the privacy of the individual.”

The forced blood draw comes from section 316.1933, Florida Statutes. The refusal crime comes from Trenton’s Law, chapter 2025-121, Laws of Florida, effective October 1, 2025, which made a first refusal of a lawful breath or urine test a second-degree misdemeanor under section 316.1939, Florida Statutes. A blood refusal is still not a crime. Our post on breath test refusal in Florida walks through the warnings an officer must give.

Can THC test results be used against you at trial?

Often, but a judge can keep them out when they mislead more than they prove. In State v. Sercey, 825 So. 2d 959 (Fla. 1st DCA 2002), an Alachua County DUI manslaughter case, the court held that standard THC testing is not novel science, so evidence of THC “is therefore admissible even if it cannot be quantitatively related to impairment, unless it is excluded under section 90.403.” The court also upheld the exclusion of expert opinions that tried to estimate when the driver last used marijuana.

Section 90.403, Florida Statutes, is the rule that excludes evidence when unfair prejudice substantially outweighs its value. In Estrich v. State, 995 So. 2d 613 (Fla. 4th DCA 2008), a Palm Beach County fatal crash case, the State introduced 39 nanograms of carboxy-THC, a THC metabolite. The evidence showed it “probably did not affect” the driver at the time of the crash, so the court held it should have been excluded and ordered new trials.

Together these cases set the defense playbook. Our attorneys at The Brancato Law Firm look at exactly what the lab measured, whether it was THC itself or a metabolite, and how long after driving the sample was taken, and we file a motion to exclude when the number cannot speak to impairment.

What is a drug recognition expert, and is the opinion reliable?

A drug recognition expert, or DRE, is an officer trained to run a 12-step evaluation and give an opinion about which drug category is impairing a driver. In Williams v. State, 710 So. 2d 24 (Fla. 3d DCA 1998), the court held that the 12-step protocol “is not ‘scientific'” and allowed the officer’s opinion that the driver was impaired by specific drug categories. The court treated the horizontal gaze nystagmus eye test as “quasi-scientific,” admissible only with a foundation that a qualified officer administered it properly. A dissenting judge warned that a DRE “is not a toxicologist.”

Williams was decided under an older standard for scientific evidence, so our attorneys challenge DRE opinions under the current rules and test whether each of the 12 steps was done and recorded. Our post on drug recognition experts in Florida explains the evaluation step by step.

Does a medical marijuana card protect you from a DUI?

No. Section 381.986(14)(g), Florida Statutes, states that the medical marijuana law “does not exempt a person from prosecution for a criminal offense related to impairment or intoxication resulting from the medical use of marijuana or relieve a person from any requirement under law to submit to a breath, blood, urine, or other test to detect the presence of a controlled substance.”

The card also does not cover use in a car. “Medical use” excludes use “In a school bus, a vehicle, an aircraft, or a motorboat,” except for low-THC cannabis not in a form for smoking, and using marijuana in a vehicle is a first-degree misdemeanor under section 381.986(12)(c). A lawful patient can still be a sober driver, though, and our attorneys at The Brancato Law Firm show the jury the difference between a patient who has THC in the body and a driver whose faculties were impaired. Possession rules for patients are covered in our guide on how to fight a marijuana possession charge in Florida, and our guide on how to legally transport medical marijuana in Florida covers the packaging rules, the registry card, and odor-based car searches.

Can you get a DUI for delta-8 or hemp products in Florida?

Possibly, and the question is unsettled. Delta-8 THC is listed in Schedule I at section 893.03(1)(c)190.a., Florida Statutes, but section 581.217, Florida Statutes provides that hemp-derived cannabinoids “are not controlled substances or adulterants if they are in compliance with this section.” A compliant hemp product therefore has a strong argument that it is not a “substance controlled under chapter 893” for the DUI statute. We have found no Florida appellate decision on that argument.

The State will answer that the product was not compliant, for example because it exceeded 0.3% total delta-9 THC or was synthesized. The federal picture also changes on November 12, 2026, when Public Law 119-37 narrows the federal definition of hemp and excludes cannabinoids synthesized outside the plant, according to the Congressional Research Service. Florida’s hemp statute does not adopt the federal text, so a Florida DUI still turns on Florida law. Hemp products in Florida are legal to sell to adults 21 and older when they meet section 581.217, but legal to buy never means legal to drive impaired. Our attorneys at The Brancato Law Firm get the product, its label, and its certificate of analysis into evidence early, because lab proof of the exact cannabinoid can decide the case.

How common are marijuana-involved crashes in Florida?

Hundreds a year. In 2023, marijuana was reported in 417 Florida crashes, down from 554 in 2020, according to the Florida Department of Highway Safety and Motor Vehicles report Impaired Driving Education Campaign, presented to the Governor and Cabinet on January 31, 2025. The same report counted 969 impaired-driving fatalities statewide in 2023, involving alcohol, drugs, or both.

These figures count crashes where marijuana was reported, and one crash can count under more than one drug. They do not show that marijuana caused the crash. Our attorneys at The Brancato Law Firm keep that distinction in front of the jury, because the State often treats “reported” as “impaired.”

What are the penalties for a marijuana DUI in Florida?

The same as for an alcohol DUI. Under section 316.193, a first conviction carries up to 6 months in jail, a fine of $500 to $1,000, probation of up to 1 year, at least 50 hours of community service, and a 10-day vehicle impoundment. DUI with property damage or injury is a first-degree misdemeanor, DUI with serious bodily injury is a third-degree felony, and DUI manslaughter carries a 4-year mandatory minimum. Our guide to the penalties for DUI in Hillsborough County covers every tier.

Your license is a separate case. If you refused a urine or breath test, your license is suspended for the refusal, and you have 10 days from the notice of suspension to request review. Our post on how to protect your driver’s license after a DUI arrest explains the choices, and our attorneys at The Brancato Law Firm handle the license review and the criminal case together.

What are the penalties for a second or third marijuana DUI in Florida?

They rise with each conviction and with how recent the last one was. Under section 316.193, Florida Statutes, a second DUI carries a fine of $1,000 to $2,000 and up to 9 months in jail, and a third DUI within 10 years of a prior conviction, or any fourth DUI, is a third-degree felony punishable by up to 5 years in prison under section 775.082, Florida Statutes. License revocation periods come from section 322.28, Florida Statutes, and they apply the same way whether the impairment came from marijuana or alcohol.

A third DUI more than 10 years after the last conviction stays a misdemeanor, with a fine of $2,000 to $5,000 and up to 12 months in jail. The court must also order an ignition interlock device for at least 1 year after a second conviction and at least 2 years after a third. These are the base penalties; a minor in the vehicle raises them. Because prior convictions drive every number in this table, our attorneys at The Brancato Law Firm pull the dates and court records of each prior before advising on any plea.

How do our attorneys fight a marijuana DUI charge?

We take apart each piece of the impairment case:

1. The stop. We review whether the officer had a lawful reason to stop the car and to extend the stop for a drug investigation.
2. The driving. We compare the arrest report with the dash camera and body camera video.
3. The roadside exercises. We check how they were explained and scored, and whether the video matches the report.
4. The DRE evaluation. We check every one of the 12 steps against the DRE’s own written record.
5. The lab. We identify whether the result was THC itself or a metabolite, when the sample was taken, and how the urine collection was handled under section 316.1932.
6. The product. For delta-8 and hemp, we test whether the substance was a controlled substance at all.
7. The science. We use the NHTSA, AAA, and JAMA Psychiatry research, with defense experts, to show why THC in the body is not proof of impairment.

What should you do after a marijuana DUI arrest in Tampa?

Move fast on the license and the evidence. A person arrested in Hillsborough County sees a judge at first appearance within 24 hours, usually at the Orient Road Jail. Then:

1. Mark the 10-day deadline if your license was suspended for a refusal.
2. Write down the timeline of when you last used any product and when you were tested.
3. Keep the product and its packaging, including any hemp label or certificate of analysis.
4. Do not discuss the case on jail calls or social media.
5. Call a DUI lawyer before the first court date, so video and lab records can be requested early.

Frequently asked questions about marijuana DUI in Florida

Can marijuana DUI charges be dropped in Florida?

Yes, when the State cannot prove impaired normal faculties, when a THC result is excluded, or when the stop is suppressed. The Brancato Law Firm puts those weaknesses in front of the prosecutor early, as described on our Tampa DUI defense page.

How long after smoking marijuana can you be charged with DUI in Florida?

Florida has no time rule; the question is whether you were impaired when you drove. In the 2022 JAMA Psychiatry simulator study, measured driving impairment was gone by 4.5 hours, and our attorneys at The Brancato Law Firm build the timeline of use, driving, and testing to show the gap.

Is refusing a urine test for marijuana a crime in Florida?

Yes, since October 1, 2025, a first refusal of a lawful urine test is a second-degree misdemeanor, and it also brings a 1-year license suspension. The Brancato Law Firm checks whether the officer gave the warnings the law requires, as our post on refusal in Florida explains.

Is a medical marijuana card a defense to DUI in Florida?

No; section 381.986(14)(g) says the medical marijuana law does not protect a patient from an impairment prosecution. Our attorneys at The Brancato Law Firm still use the patient’s records to explain why THC was present without impairment, and our marijuana possession guide covers the card’s limits.

Can you get a DUI for delta-8 in Florida?

You can be arrested for it, but whether a compliant hemp product is a “controlled substance” under the DUI statute is unresolved in Florida’s appellate courts. The Brancato Law Firm gets the product tested and challenges the State’s proof of what the driver actually used.

Does a drug recognition expert’s opinion prove I was high?

No; it is one officer’s opinion, and a Florida court has held the 12-step protocol “is not ‘scientific.'” Our attorneys at The Brancato Law Firm cross-examine DREs step by step, as described in our post on drug recognition experts.

Will a marijuana DUI suspend my license in Florida?

It can, through a refusal suspension at arrest or a revocation after conviction. The Brancato Law Firm requests the license review within the 10-day window and coordinates it with the criminal defense, and our DUI license guide explains the options.

I’m Rocky Brancato, founder of The Brancato Law Firm, P.A., a Tampa criminal defense firm. I have served as a police academy legal instructor teaching officers the constitutional limits of search, seizure, and arrest, and I served as Chief Operating Officer of the Hillsborough County Public Defender’s Office. Today our attorneys defend gun and drug charges across Tampa Bay, and this question — marijuana and guns — now sits at the center of one of the fastest-moving areas in criminal law.

What Does Federal Law Say About Marijuana Users and Guns?

Federal law makes it a crime for any person “who is an unlawful user of or addicted to any controlled substance” to possess a firearm or ammunition. That ban lives in 18 U.S.C. § 922(g)(3), and because marijuana remains a controlled substance under federal law, it has always applied to marijuana users — including Florida’s hundreds of thousands of registered medical marijuana patients. A state card has never been a defense to the federal statute, because Florida’s medical marijuana program does not change what federal law says.

The federal ban shows up in a second place that trips up ordinary gun buyers: ATF Form 4473, the questionnaire every purchaser completes at a licensed dealer. The form asks directly whether you are an unlawful user of marijuana or any other controlled substance, and it warns that marijuana remains federally unlawful regardless of state medical programs. Answering falsely is a separate federal felony. Our attorneys have seen careful, law-abiding people put themselves in federal jeopardy with one checkbox — which is why the Supreme Court’s 2026 decision matters so much, and why it must be read carefully rather than treated as a green light.

What Did the Supreme Court Decide in United States v. Hemani?

In United States v. Hemani, No. 24-1234 (U.S. June 18, 2026), the U.S. Supreme Court held that the government’s prosecution of a regular marijuana user under § 922(g)(3) violated the Second Amendment — the first time the Court has struck down the application of a federal gun ban to drug users. Ali Hemani was prosecuted for having a gun in his home while being a regular marijuana user; the government’s theory was that regular use of a controlled substance, by itself, was enough to disarm him. It did not claim he was addicted, that he was high when found with the gun, or that he posed any particular danger.

Justice Gorsuch’s majority opinion, affirming the Fifth Circuit 7-2, rejected that theory under the historical-tradition test. The government leaned on founding-era “habitual drunkard” laws, but the Court found those laws targeted people whose drinking left them “practically incapacitated and incapable of managing their affairs” — not everyone who drank regularly. The Court also stressed how the modern statute operates: it “automatically divests an individual of his constitutional right to bear arms the moment he becomes an unlawful user . . . all without any pre-deprivation process,” while the historical laws required some proceeding — a conviction, a guardianship, a hearing — before anyone lost liberty. And the Court pointed out that the government’s own conduct undercuts the claim that all marijuana users are categorically dangerous: federal prosecutors have been directed to curtail enforcement against marijuana users, most states have legalized some use, and the government itself recently moved certain marijuana products down the federal schedules.

For Florida gun owners who hold medical marijuana cards, the practical takeaway is this: after Hemani, a federal prosecution built on nothing more than the fact that you regularly use marijuana is unconstitutional. That is a real shield. But it is a shield with defined edges, described next.

What Did Hemani Leave Undecided?

Hemani was an as-applied ruling, not a repeal — § 922(g)(3) is still on the books, and the Court expressly reserved several theories the government may still pursue. Anyone mixing marijuana and firearms in Florida should understand exactly where the line now sits.

That last row deserves emphasis. Nothing in Hemani changed the purchase paperwork. Until ATF revises Form 4473, a medical marijuana patient who answers “no” to the unlawful-user question is still committing a federal crime, whatever the Second Amendment now says about possession prosecutions. This is exactly the kind of trap where getting legal advice before you act is worth far more than defending a charge afterward.

Does a Florida Medical Marijuana Card Take Away Your Gun Rights?

No — holding a Florida medical marijuana card does not, by itself, disqualify you from owning or possessing a firearm under Florida law. Florida’s medical marijuana statute, Fla. Stat. § 381.986, created a physician-certification system with a patient registry, and nothing in Florida’s gun statutes makes registered patients prohibited possessors.

Florida’s concealed-carry licensing statute, Fla. Stat. § 790.06, does contain drug-related disqualifiers that patients should know about. The Department of Agriculture must deny a license to an applicant who “chronically and habitually uses alcoholic beverages or other substances to the extent that his or her normal faculties are impaired,” and to anyone found guilty of a chapter 893 drug crime within the three years before applying. A conviction for a controlled-substance offense also triggers revocation of an existing license. So while the card itself is not a disqualifier, a marijuana-related conviction — even a misdemeanor — can cost you your carry license for years.

Where Is Medical Marijuana Use Still Illegal Even With a Card?

A Florida medical marijuana card authorizes “medical use” — and the statute defines that term to exclude specific places, so using marijuana in the wrong location remains a crime even for a fully registered patient. Under § 381.986, “medical use” does not include using or administering marijuana on public transportation, in any public place, in an enclosed indoor workplace, on school grounds, or — critically for Tampa Bay’s boaters and drivers — “in a school bus, a vehicle, an aircraft, or a motorboat,” with a narrow exception for low-THC cannabis not in a form for smoking. A qualified patient who uses marijuana in plain view of the public or in a vehicle or boat commits a first-degree misdemeanor.

The Sixth District Court of Appeal enforced exactly this limit in Tanaka v. State, No. 6D2024-1581 (Fla. 6th DCA June 19, 2026), a Collier County case where the court affirmed a conviction by quoting the statute’s rule that “medical use” does not cover marijuana in a vehicle, aircraft, or motorboat. The lesson for the hundreds of thousands of Floridians with cards: your protection travels with the statute’s definitions, not with the card in your wallet. Smoking in your car — parked or moving — is outside the program, and once an officer smells it, you may face both the misdemeanor and a vehicle search. Our attorneys have litigated where the odor-of-cannabis doctrine now stands in the Tampa Bay area; see our analysis of Florida’s Second DCA limiting the plain-smell doctrine.

Can 18-to-20-Year-Olds Carry a Concealed Gun in Florida Now?

As of mid-2026, Florida’s ban on concealed-carry licenses for adults under 21 has been declared facially unconstitutional by one of Florida’s appellate courts — a major shift, though not yet a statewide settled rule. In Eubanks v. State, No. 4D2025-1698 (Fla. 4th DCA June 17, 2026), a Broward County prosecution for carrying a concealed firearm, the Fourth District held that § 790.06(2)(b) — which requires concealed-carry applicants to be 21 — “is facially unconstitutional as it relates to 18- to 20-year-olds.” The court reasoned that 18-to-20-year-olds are part of “the people” the Second Amendment protects, that the State produced no historical tradition of categorically disarming young adults, and — quoting the U.S. Supreme Court’s Rahimi decision — that a group cannot be “disarmed simply because he is not ‘responsible.’” The court reversed the young man’s conviction outright.

Two cautions before anyone under 21 straps on a holster. First, Eubanks is a Fourth District decision; Tampa, Hillsborough, Pinellas, and Pasco Counties sit in the Second District, which has not yet spoken, and the State may seek further review in the Florida Supreme Court. Second, the decision addressed concealed carry — it did not touch Florida’s open-carry ban or the separate federal rules for handgun purchases by under-21 buyers. Anyone in that age group facing a carry charge should treat Eubanks as a powerful defense to raise, not a settled right to rely on. For the broader landscape — permitless carry under Fla. Stat. § 790.01, where guns are still prohibited, and how gun charges are penalized — see our guide to gun crime laws in Florida.

How Do These Decisions Change a Florida Gun Charge Defense?

They add constitutional attacks to a defense toolbox that already starts with the Fourth Amendment. When our attorneys defend a Tampa Bay gun charge involving marijuana, the analysis now runs on three tracks at once.

1. Was the stop and search lawful? Most marijuana-and-gun cases begin with a traffic stop, a pat-down, or a search justified by the smell of cannabis. If the stop was unlawfully prolonged or the frisk exceeded its limits, the gun itself can be suppressed — see our breakdown of stop and frisk law in Florida.
2. Is the charge constitutional after Hemani and Eubanks? A federal § 922(g)(3) charge premised on use alone is now unconstitutional as applied. A state concealed-carry charge against an otherwise law-abiding 18-to-20-year-old is squarely challenged by Eubanks. These arguments are raised by motion — and where a district conflict exists, preserving the issue protects your appeal.
3. Does the statute even fit the facts? Was the marijuana “medical use” within § 381.986? Was the firearm actually “possessed”? Was a license exception satisfied? The State must prove every element, and pre-file advocacy — engaging the State Attorney’s Office before charges are formalized — can resolve borderline cases before they ever reach a courtroom.

What Should You Do If You Are Arrested on a Marijuana-Related Gun Charge?

Move fast, and say nothing about your marijuana use to anyone but your lawyer. Statements about how often you use — the exact fact that decides whether the government can build a lawful case after Hemani — are routinely volunteered in the first police interview, and they are admissible. In Hillsborough County, a felony gun arrest means booking at Orient Road Jail, first appearance within 24 hours, and formal charging decisions by the State Attorney’s Office in the weeks that follow. That charging window is where an early defense presentation can change everything: our attorneys use it to put suppression problems, Hemani and Eubanks issues, and medical-marijuana documentation in front of the prosecutor before the filing decision is made. If you were just arrested, our step-by-step guide to what to do after being arrested in Tampa walks through the first 72 hours.

Frequently Asked Questions

Can I buy a gun in Florida if I have a medical marijuana card?

Florida law does not prohibit the purchase, but the federal purchase form still asks whether you are an unlawful user of marijuana, and marijuana remains federally unlawful even for state medical patients. Answering falsely on ATF Form 4473 is a federal felony that Hemani did not eliminate. Our attorneys advise cardholders on lawful paths before purchase, because this is far easier to get right in advance than to defend afterward.

Did the Supreme Court legalize gun ownership for all drug users?

No. United States v. Hemani, No. 24-1234 (U.S. June 18, 2026), held only that prosecuting a person for regular marijuana use alone violates the Second Amendment. The Court expressly left open prosecutions of people who are addicted, armed while presently intoxicated, or shown by individualized proof to be dangerous — and it did not touch the felon-in-possession ban.

Can I keep a gun in my car along with my medical marijuana?

Carrying a firearm in your vehicle can be lawful under Florida’s permitless-carry framework, but using marijuana in a vehicle is never “medical use” under Fla. Stat. § 381.986 — it is a first-degree misdemeanor even for cardholders. Combining the two also invites a search and a charging decision that treats you as an unlawful user. Keep the marijuana sealed, in its original packaging, and never use it in the car or on a boat.

Can an 18-year-old legally carry a concealed gun in Florida in 2026?

The Fourth District held in Eubanks v. State that the 21-and-over rule in § 790.06(2)(b) is facially unconstitutional, but that ruling comes from South Florida’s appellate district and the issue is not finally settled statewide. In Tampa Bay — the Second District — prosecutors may still file the charge, and the defense must raise Eubanks by motion. The Brancato Law Firm, P.A. litigates these constitutional challenges and preserves them for appeal.

Will a marijuana conviction cost me my concealed weapons license?

Yes — a finding of guilt for a chapter 893 drug crime requires revocation of a Florida concealed-carry license, and it bars a new license for three years under Fla. Stat. § 790.06. That collateral consequence is one more reason to fight a “minor” possession charge rather than plead it out quickly. We routinely defend possession cases with the license consequences as a central goal.

Does Florida report medical marijuana patients to the federal government?

Florida’s medical marijuana use registry is a state system, and Florida law treats patient records as confidential; the registry is not a public list handed to federal authorities. But dispensary purchases, statements to police, and social media can all establish “unlawful user” status in a federal case. If you hold a card and own firearms, The Brancato Law Firm, P.A. can walk you through how the two programs actually interact.

Marijuana-and-gun law is moving faster right now than at any point in decades — Hemani and Eubanks both landed within a single week of June 2026, and the next round of decisions will decide how far they reach in Tampa Bay. If you are facing a gun or marijuana charge, or you hold a medical card and want to keep your gun rights intact, call the attorneys of The Brancato Law Firm, P.A. — founded by Tampa Criminal Defense Attorney Rocky Brancato — at (813) 727-7159 today.

Most odor-based car searches in Tampa Bay are won or lost on the first ninety seconds of body-camera video. As founder of The Brancato Law Firm, P.A., a Tampa criminal defense firm, and a former police academy instructor who taught criminal procedure, I know how officers are trained to build a search from a smell, and I have spent more than 25 years in Hillsborough County courtrooms. Our attorneys review the recording of every odor-based stop for the moment that training shows.

Can Police Search Your Car Just Because It Smells Like Marijuana?

Not in Hillsborough, Pinellas, or Pasco County — the odor of cannabis, standing alone, no longer establishes probable cause here. In Williams v. State, 421 So. 3d 809 (Fla. 2d DCA 2025) (en banc), the Second District Court of Appeal — the appellate court covering Tampa Bay — sitting en banc, held that “the smell of cannabis standing alone is insufficient to establish probable cause,” receding from its own prior precedent.

The reason is simple chemistry meeting new law: since Florida legalized medical marijuana and hemp, a trained officer cannot tell by smell whether the odor comes from something illegal or something perfectly lawful. The smell no longer makes contraband “immediately apparent” — so it can no longer do the work of probable cause by itself. Odor remains a relevant factor, but it must be combined with something more. Our attorneys have been filing suppression motions built on Williams since the week it came down, and our Tampa drug crimes attorney page explains how those motions fit into a full drug defense.

What Happened in Williams — and Why the Evidence Still Came In

Williams began the way these cases usually do: a 2023 traffic stop in Hillsborough County where officers said they smelled cannabis and searched on the odor alone — no admission of use, no indication whether the smell was hemp, medical marijuana, or illegal cannabis, and no evidence of recent smoking in the vehicle. The en banc court used the case to recede from Owens v. State, 317 So. 3d 1218 (Fla. 2d DCA 2021), its 2021 decision holding that the legalization amendments didn’t change the Fourth Amendment analysis.

But there is a catch every reader should understand: the defendant in Williams still lost. Because the officers searched at a time when the old rule (Owens) was still binding precedent, the court applied the good-faith exception — evidence is not suppressed when officers act in objectively reasonable reliance on the appellate law in force at the time of the search. The practical translation: the new rule protects people searched after October 1, 2025, far more than those searched before. And because the change is so consequential, the court certified the question to the Florida Supreme Court as one of great public importance: does the plain smell doctrine continue to apply based only on the odor of cannabis? As of November 2026, the Florida Supreme Court has not answered that question, and this page will be updated when it does.

When Can Odor Still Justify a Search? The Cherfils Lesson

When the smell comes with other facts — and in Cherfils v. State, No. 2D2023-1932 (Fla. 2d DCA Dec. 31, 2025), the same court showed exactly how that happens. Joshua Cherfils was stopped in a high-crime area for an improperly illuminated license tag. The officer smelled burnt marijuana. Cherfils became argumentative and nervous, then produced his medical marijuana card and admitted smoking earlier in the day — but the officer testified the odor was “a lot more than just if someone smoked earlier.” The court held that, under the totality of the circumstances, the officer could reasonably conclude Cherfils had been illegally smoking marijuana in the vehicle — and upheld the search.

The Brancato Law Firm, P.A. — Tampa search and seizure defense — (813) 727-7159

Read Williams and Cherfils together and the rule for our district is clear: smell alone loses; smell plus your own words and behavior can win — for the State.

Why Showing Your Medical Marijuana Card Can Backfire

Because the card converts a legally ambiguous smell into evidence of a crime. Hemp, which section 581.217, Florida Statutes, defines as cannabis with a total delta-9 THC concentration of no more than 0.3 percent on a dry-weight basis, is legal to possess and use almost anywhere. Medical marijuana is legal to possess, but section 381.986(12)(c), Florida Statutes, makes it a first-degree misdemeanor for a patient to use it in a vehicle. When Cherfils volunteered his card and his earlier smoking, he eliminated the innocent explanation (hemp) and handed the officer reason to believe the smell came from marijuana smoked in the car.

This is the counseling moment our attorneys wish more drivers got in advance: the Second District’s new rule is powerful, but nearly every case that loses under it loses because of what the driver said in the first ninety seconds of the stop.

The card question reaches a large share of Florida drivers. As of October 30, 2026, 943,844 qualified patients held active medical marijuana ID cards in Florida, according to the Florida Department of Health’s Office of Medical Marijuana Use weekly update. Each of those cardholders can hand an officer the same extra fact Cherfils did, which is why our attorneys treat the card as something to explain through counsel, after the stop.

August 2026 Update: Other Districts Keep Upholding Odor-Based Searches

Outside the Second District, Florida’s appellate courts are continuing to uphold vehicle searches built on the smell of marijuana, most recently in Ptomy v. State, No. 1D2025-1029 (Fla. 1st DCA Aug. 19, 2026). In that Escambia County appeal, the First District affirmed without a written opinion, citing decisions that judge odor-based vehicle searches under a totality-of-the-circumstances approach.

The decisions Ptomy cited show where the rest of the state stands: Aldama v. State, 394 So. 3d 148 (Fla. 3d DCA 2024), which found probable cause where the driver denied having a medical marijuana card or medical marijuana in the car — answers that ruled out any lawful source for the smell — and Hoehaver v. State, 389 So. 3d 766 (Fla. 5th DCA 2024), which held that the odor of burnt marijuana coming from inside a vehicle supplied probable cause. Notably, the Fifth District has also held en banc — in Baxter v. State, 389 So. 3d 803 (Fla. 5th DCA 2024) — that because the plain smell of cannabis is no longer clearly indicative of criminal activity, the odor alone cannot even supply reasonable suspicion for an investigatory stop. So even outside Tampa Bay the direction of travel is the same: the smell needs company.

Here is the statewide picture as of August 2026:

The Brancato Law Firm, P.A. — (813) 727-7159

The practical lesson hasn’t changed — it has sharpened. In every district, what you say during the stop is what converts a smell into a search. Until the Florida Supreme Court answers the certified question from Williams, the rule genuinely depends on where you were stopped — and our attorneys apply the right district’s law to every suppression motion we file.

What Do Officers Have to Show Now?

Facts beyond the smell — articulated specifically, not recited from training. Since Williams, an officer in our district who writes “I detected the odor of marijuana” and nothing more has written a suppression motion for the defense. What the case law now separates:

The Brancato Law Firm, P.A. — Tampa drug and search defense — (813) 727-7159

When our firm litigates these motions, the body camera is the battleground: the report’s neat “totality of circumstances” often turns out, on video, to be an odor and nothing else. That is a winnable case in the Second District today.

What Should You Do If Your Car Was Searched Based on Smell?

Get the search reviewed now, because the timing of your stop controls which rule applies. Searches conducted after October 1, 2025, in Hillsborough, Pinellas, or Pasco County are governed by Williams — odor alone is not probable cause, and a motion to suppress may take the State’s evidence off the table entirely. Earlier searches face the good-faith exception, but may have other defects: an unlawful stop, an overlong detention, or “additional factors” that exist only in the report. Bring the paperwork and any recording to counsel before your arraignment; suppression issues are won by lawyers who get to the video early.

Frequently Asked Questions: Cannabis Odor and Car Searches in Florida

Can police search my car for smelling marijuana in Florida?

Not based on the smell alone in the Tampa Bay area — Williams v. State ended that in October 2025. But odor combined with other factors, especially your own statements, can still justify a search, and other Florida districts continue to uphold odor-based searches. Our attorneys evaluate exactly which rule applied to your stop.

What is the plain smell doctrine?

It was the rule that the smell of cannabis, by itself, gave officers probable cause to search — treating the odor as automatically incriminating. The Second District receded from it in Williams because legal hemp and medical marijuana are indistinguishable from illegal cannabis by smell. Odor is now just one factor in the totality of the circumstances.

Should I show my medical marijuana card during a traffic stop?

Be very careful — in Cherfils, producing the card helped establish probable cause, because it signaled the smell came from medical marijuana, which is illegal to smoke in a vehicle. You are not required to explain a smell. In our cases, the card is best presented by counsel, in context, after the stop.

Does this ruling make marijuana legal in Florida?

No. Possession remains illegal except for medical marijuana obtained through a licensed dispensary and hemp within legal THC limits. Williams changed what justifies a warrantless search — not what is legal to possess.

Does the Williams rule apply everywhere in Florida?

No. Williams and Cherfils bind the Second District — Hillsborough, Pinellas, and Pasco among its counties — while the First, Third, and Fifth Districts have all recently upheld odor-based searches where the smell was burnt or the driver’s answers ruled out a legal explanation (Ptomy, Aldama, Hoehaver). Until the Florida Supreme Court answers the certified question, the rule depends on where you were stopped — and our attorneys brief the right district’s law in every motion.

What if my car was searched based on odor before October 2025?

The good-faith exception likely protects that search from suppression on odor grounds alone, because officers were relying on the law in force at the time — that is exactly what happened in Williams itself. But earlier searches often have other problems worth reviewing: the lawfulness of the stop, the length of the detention, and whether the claimed “additional factors” hold up on video.

Can a drug charge be dropped if the search was illegal?

Often, yes — when a suppression motion removes the drugs from evidence, the State frequently cannot proceed. The Brancato Law Firm, P.A. has litigated suppression in Tampa Bay courtrooms for decades, and post-Williams odor searches are among the most suppressible cases we see.
